Want to publish a NIH-funded paper in Nature? Well - unless your institution has an agreement with Springer, you'll have to be mega-rich to be compliant with NIH's new no-embargo policy. Springer is insisting on gold OA - that's $12,690 and that's extortion.
This is a useful summary of how some major publishers are responding to the new NIH policy. We've just updated our policies at @biologists.bsky.social: @dev-journal.bsky.social @jcellsci.bsky.social and @jexpbiol.bsky.social will allow authors to deposit the accepted version with zero embargo.

Trump's illegal NIH cuts mean cancer researchers would be laid off, sick kids going without treatment, and more. These cuts would be DEVASTATING for lifesaving research.

Some Republicans have said they agree—but they just blocked my amendment to reverse Trump's NIH cuts anyway.
